To all whom it may concern:

Be it known that I, AUcUsTE VINoENT, a citizen of the French Republic,residing at Chateaubriant, (Loire Inl'rieure,) France, have inventedcertain new and useful Improvements in Machines for Finishing TextileFabrics, of which the following is a specification.

My invention has for its object to provide an improved machine fordressing and finishing woven fabrics.

My machine relates to that class wherein the fabric, after having beenmoistened, is carried around a heated cylinder, being held against thesame by an endless apron of absorbent material, which apron is supportedon suitable rollers. The fabric is in this way dried and smoothed, andthe desired finish is imparted to it.

Figure 1 of the accompanying drawings is a front elevation of themachine. Fig. 2 is an elevation of the right'haud end of the machine.Fig. 3 is a similar elevation of the left-hand end of the machine. Fig.4is a vertical transverse mid-section of the machine. Fig. 5 is afragmentary sectional detail view. Fig. 6 is an enlarged cross-sectionof the sprayer; and Fig. 7 is a fragmentary elevation corresponding topart of Fig. 2, and showing a modification.

A A are two cast-iron frames at opposite sides of the machine, bearingthe working parts. Alarge hollow cylinder or drum, I, is mounted betweenthe frames, its journals being hollow and receiving steam to heat thecylinder.

In front of the drying-cylinder I is a roller, K. Above it are tworollers, Q Q, behind it is aroller, It, and beneath it is a roller, S.An endless apron, I, made of absorbent fabric, woolen felt beingpreferred, is passed almost entirely around the cylinder I, from theroller K to the roller Q, and thence outside of the rollers Q, Q, It,and S back to and around roller K. The apron is kept strained by one ofthe rollers-the roller S in the construction shown-being provided withsliding bearingblocks engaged by screws a a. To facilitate the turningof these screws to adjust the rollers S, they are geared bybevel-pinions Z to ahorizontal shaft, it, which may be turned by anyknown means, as a crank or key, to movethe roller S.

The roll of fabric to be treated is placed in bearings at the front ofthe machine, as shown at M, and is subjected to tension by means of ascrew,s,(seen in Fig. 1,) which may be set up to press more or lessagainst the end of the cylinder upon which the fabric is wound. Thefabric passes first over a guidingroller, N, thence over a sprayer, O,by which it ismoistened, and thence it passes around the dryingcylinderI, being held against the same by the apron 1 Thus the fabric is firstmoistened by the sprayer, and then smoothly dried by the heat from thecylinder 1, which drives its moisture out, the apron P acting to absorbthe moisture from the fabric, and being itselfdried again during itspassage back over the outer rollers, Q, Q, It, and S. The finishedfabric is carried back over the top of the apron, as shown by the dottedline in Fig. 4. The sprayer 0 consists of a hollow prism or tube fixedimniovably in place and perforated on its upper side. It receives steamat its end and discharges it upwardly in jets through these perforationsagainst the fabric which is passing over it.

So far as described, this machine is of the ordinary construction. Inmachines of this character, as heretofore constructed, the apron I haspassed around and over the sprayer 0, so that the steam or vapor fromthe sprayer has had to pass first through the absorbent apron before itcould reach the fabric to be treated, whereby the apron was renderednecessarily more moist than the fabric. It is desirable that the steamshall pass through a textile fabric before it reaches the fabric to betreated, but it is not desirable that the apron shall be wetted, for thereason that it is thereby unfitted for absorbing moisture from thefabric under treatment, it being necessary for the heat from thecylinder I to expel both the moisture in the fabric lying next it andthat in the apron outside, which requires either a higher degree of heator a longer time than is desirable.

It is one object of my invention to acceler" ate the operation byavoiding the wetting of] this frame is shown in section in Fig. 5.

the apron, which I accomplish by arranging the sprayer outside theapron, and I facilitate the drying of the apron and its absorption ofmoisture from the fabric under treatment by heating the roller K, andforcing it with considerable pressure against the eylinder I, so thatthe moist fabric is pressed close against the dry and absorbent apron attheir first contact with the cylinder I. I effect the requisitestraining of the steam from the sprayer through a fabric before itreaches the fabric under treatment by wrapping it permanently with atextile covering ofits own.

I will now proceed to describe the novel features and the constructionof my machine more in detail. The sprayer O is made, preferably, ofcopper and of triangular form in cross-section. Steam is admitted to itsinterior through a passage (shown'in dotted lines in Fig. 4) leadingfrom the bearing of the cylinder K, and its upper sideis perforated. Thesprayer is wrapped with a thin fabric, f, as shown in Fig. 6, which actsto sift and partially condense the steam as it passes through theperforations and before it comes in contact with the fabric undertreatment. The roller or cylinder K is made hollow and receives steamthrough its journal. It is preferably made of cast-iron,while thecylinder I is preferably made of copper. The steam from these cylinderscomes from a pipe, g, which is divided into two branches, 1' and s, theformer leading to the bearing of the cylinder K, the latter to thebearing of the cylinder I, Fig. 2, and each being provided with a valveor stop-cock, 1), Fig. 1, by which the admission of steam to thecylinders may be controlled. The heated roller or cylinder K is pressedagainst the cylinder I with a yielding pressure, such as is afforded byweights or springs, and thus acts to squeeze-together the hot, dry apronand" the moist fabric, which not only accelerates the drying of thelatter, but compacts and smooths it. The roller K is mounted movably, sothat the operator can draw it away from the cylinder I at will againstthe pressure which is tending to force it toward the cylinder I. It isnecessary to draw the roller K away from cylinder I in entering a newlength of fabric and at other times, and at such times it is desirableto have the apron P separated from the cylinder I .at the place ofentrance of the fabric. This I accomplish by carrying the bight of theapron over the roller K, so that when the latter is moved away from thecylinder the apron moves with it. In prior machines of this class theapron has been carried at the'front over two rollers in fixed bearings.

The construction which I have designed for effecting the pressure of theroller K and its retraction will now be described. A frame, V, isarranged at the front of the machine, and is mounted upon tracks or'slideways formed upon the frames A A, so that it may slide backward andforward thereon. Onesideof Weights W W, suspended by chains w x, arearranged to press the slide-frame V backward, and thus press thecylinder K against the cylinder I. The proper pressure is obtained byincreasing or decreasing the weights. The chains as as wind partlyaround wheels '1; v, to which their ends are fixed, and to these wheelsare fixed, respectively, two hand-levers, J J, by hearing down on whichthe wheels '0 c are turned and the weights raised until the notches z zin the wheels 1) o are engaged by pawls w m, pivoted to the fixed frame,and are thus held from turning backward and dropping the weights. Eachlever J has an arm, z, which takes against a pin or pins, 25, on theslideframe V, in order to move the latter forward or press it back. Thepinst are best shown in Fig. 3,where the wheel 12 is broken away toexpose them to view. To drop the weights and press the dryingcylinderstogether again,

the pawls w are withdrawn, and the weights lowered by means of thelevers J. 4

Any other known mechanical connection may be employed for transmittingthe pressure of the weights to the slide-frame V, and for drawingforward the slideframe and holding it. As an instance of one suchmodification, I show the construction illustrated in Fig. 7, where theweight is placed on the end of a'lever, J, extending backwardhorizontally, which lever is formed at its fulcrum with a toothedpinion, '0, engaging a rack, 0 upon the frame V. The lever is extendedforward to form a handle, J, by pressing down on.

which the weight may be raised. The pawl or stop :10, for holding theslidefi'ame forward, is here attached to the lever, and engages a fixedtooth, z, on the frame.

The cylinder I may be revolved by any suitable known means under thecontrol of the operator. In prior machines of this class the cylinderhas sometimes been driven by power through the medium of frictionalspeed-regulating gearing. I have shownin the drawings a treadle fordriving the cylinder by the foot of the attendant. The shaft of thetreadle B is mounted between the frames A A, and is connected through apitman, O, with a crank, D, Fig. 1, on the shaft of which is fixed apinion, E, and fly-wheel D. The pinion E drives a gear-wheel, E, fixedon the same shaft with a pinion, F, Fig. 3, w hich drives an idler-gear,G, and this in turn drives a gear-wheel, H, fixed on the shaft of thecylinder I.

In order to enable fresh pieces of fabric to be dressed, a cylinder, X,Fig. 3, may be added at a distance of fifteen to twenty centimeters tothe rear of the roller B, it being made of the same diameter as thelatter, and turned at the same speed by means of a belt. (Shown indotted lines in Fig. 3, lettered If.) The fabric in leaving the machinewill then follow the course shown in dotted lines ate in Fig. 4, wherebythe roller X serves to facilitate its separation from the apron 1?.

My machine is to be distinguished from the chines for dressed or glazedfabrics the fabric' has first been sprayed before passing over theheated surfaces, and that the heated smoothing or polishing irons havebeen pressed against a heated cylinder by yielding pressure, and that ahand-lever has been arranged to throw off this pressure. I make no claimto these features as my invention.

I claim- 1. The combination, with a heated dryingcylinder, I, rotativelymounted, an endless apron of absorbent fabric passing almost entirelyaround said cylinder-,rollers for supporting and guiding said apron, anda spraying device for moistening the fabric under treatment, of a heateddrying-roller, K, arranged against the cylinder I, means for pressingsaid roller against said cylinder with a yielding pressure, the bight ofthe apron passing over said roller, whereby the apron is simultaneouslyheated and pressed with the fabric under treatment against thedrying-cylinder I, and mechanism connected to said roller K andadapted,when moved by the operator,to draw said roller away from thecylinder I, thereby parting the bight of the apron therefrom,substantially as and for the purposes set forth.
